/**
 * Variant of JSR-303's {@link jakarta.validation.Valid}, supporting the
 * specification of validation groups. Designed for convenient use with
 * Spring's JSR-303 support but not JSR-303 specific.
 *
 * <p>Can be used e.g. with Spring MVC handler methods arguments.
 * Supported through {@link org.springframework.validation.SmartValidator}'s
 * validation hint concept, with validation group classes acting as hint objects.
 *
 * <p>Can also be used with method level validation, indicating that a specific
 * class is supposed to be validated at the method level (acting as a pointcut
 * for the corresponding validation interceptor), but also optionally specifying
 * the validation groups for method-level validation in the annotated class.
 * Applying this annotation at the method level allows for overriding the
 * validation groups for a specific method but does not serve as a pointcut;
 * a class-level annotation is nevertheless necessary to trigger method validation
 * for a specific bean to begin with. Can also be used as a meta-annotation on a
 * custom stereotype annotation or a custom group-specific validated annotation.

/**
 *JSR-303的{@linkjakarta.validation.Validity}的变体，支持
 *验证组的规范。专为方便使用而设计
 *Spring的JSR-303支持，但不是JSR-303特定的。
 *
 *＜p＞可以与Spring MVC处理程序方法参数一起使用。
 *通过｛@link org.springframework.validation.SmartValidator｝的支持
 *验证提示概念，其中验证组类充当提示对象。
 *
 *<p>也可以与方法级验证一起使用，表明
 *类应该在方法级别进行验证（充当切入点
 *对于相应的验证拦截器），但也可以选择指定
 *注释类中用于方法级验证的验证组。
 *在方法级别应用此注释允许重写
 *特定方法的验证组，但不作为切入点；
 *然而，类级注释对于触发方法验证是必要的
 *对于一个特定的bean。也可以用作
 *自定义构造型注释或自定义组特定验证的注释。
